With window managers, I used a script to open xterm and ask me to
{shutdown, reboot, close session}. Then, noticed several Live CDs, such
as pmagic (and systemrescuecd, if I recall correctly), which used small
scripts in xdialog. I know other distribution Live CDs with the same,
but do not remember now. That what I am using now, but with mouse click.
It would be possible possible for a initial script to test for X and
then execute for console or X, I believe.
